3 Claims.

The present invention relates to a rectangular the cover are bent at spaced intervals at 23 box formed of sheet metal or other suitable material and has particular reference to a hinged box of simple construction.

' The principal object of the present invention is the provision of a rectangular box having a one-piece cover hingedly connected to one side of the body and having extension ledge flanges for engaging the interior of the box to hold the I cover in closed position.

An important object of the invention is the provision of a rectangular box having a hinged one-piece cover of simple construction adapted to snap into a closed position on the box.

Numerous other objects of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawing, discloses a preferred embodiment thereof.

Referring to the drawing:

Figure 1 is a perspective view of a rectangular box embodying the present invention; and

Fig. 2 is an enlarged transverse sectional view of the box with its cover in closed position being taken substantially along the lines 22 in Fig.

1, a part of the box body being broken away.

The present invention relates to a simple and efficient form of sheet metal box having a hinged lid or cover which is formed with projecting flanges adapted to fit inside of the upper edge of the box body when the cover is in closed position, this fit providing a snapped frictional engagement with parts of the body to hold the cover against accidental opening during shipment and other handling.

The box shown in the drawing for the purpose of illustrating the present invention comprises a body 11 to which is secured a bottom or end member 12 which may be united to the lower edge of the body in any suitable manner, as by inter-folding of the edges in a double seam 13. The upper edge of the body ll along three of its sides is curled inwardly at 14 and along its fourth side is formed with spaced projections 1 15 which are bent over and inwardly to enclose a wire pintle 16.

A one-piece cover 17 is formed with a central panel 18 which is surrounded by extension ledges 19, formed by reversed bends or folds of the edges of the cover member as best illustrated in Fig. 2. The extension ledges 19 are further extended along three sides and are bent at right angles thereto to form flanges or walls 21, the terminal edges of which are curled at 22.

The extension ledge 19 along the fourth side of around the wire pintle 16 and intermediate the projections 15. In this manner the cover 17 is hinged along one side of the body 11, the extension ledge 19 adjacent the hinged side of the cover and box providing a stop for holding the cover in its raised or open position, as illustrated in Fig. 1.

When the cover member is closed on the box, the curled edges 22 of the walls 21 along the three sides of the box engage under the curls 14 formed on the three sides of the body 11. The cover walls 21 are of sufficient resiliency to permit a snapping under of their edge curls 22 as the cover is brought into closed position, after which the cover member remains locked in this closed position on the body until forcibly opened.

The closed box may be inverted even when filled without fear of accidental opening of the cover since the resiliency of the walls 21 is sufficient to support a reasonable weight against the inside of the cover. A relatively, slight lifting force applied under the front extension ledge 19 of the cover member disengages the curled edges 14 and 22 and permits further hinging of the cover to open the box.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

I claim:

1. A rectangular box, comprising a body having an inwardly doubled top edge, and a cover hinged to the opposite edge of said body, said cover having marginal flat folds at its edges extending outward beyond the sides and ends of the box, said cover being provided with a flange downwardly extending at the inner edge of the fold and having its lower edge doubled outward and upward to form an edge of double thickness for interengagement beneath the said doubled portion of the body.

2. A rectangular box, comprising a body inwardly curled at its top about three of its edges, and a cover hinged to the fourth edge and depressed at its margin above the top of the box and having its marginal edges folded upon themselves to provide flat extension ledges engaging on top of the curls of said edges of said body, three edges of said cover being curled outward and upward to form an edge of double thickness and adapted to extend down within said body in interengagement under the curls of the edges of said body.

3. A rectangular box, comprising a body and a cover hinged along the side of said body, said cover being substantially fiat and having its
